I use ubuntu 18.4.04 LTS. But now I want to learn ethical hacking and cybersecurity. And also use it because collage take class using Zoom meeting, which is not safe according to news. So I want to use Kali Linux. Sometimes ago I want to use Windows 10 and Ubuntu dual boot. But I learn that dual boot is risky. So I didn't do this. But I can't find is it safe to do dual boot Kali Linux and Ubuntu? Can anyone tell me is the dual boot of kali Linux and Ubuntu safe or not?
I previously use ubuntu os. But it is very difficult to find something for ubuntu then windows. And my college their use Windows. And as maximum place windows is use and maximum youtube tutorial available for Windows, I change my os to Windows. But I love Ubuntu. and for codding ubuntu is much better than windows. So I use ubuntu using flash drive to run ubuntu.
So if I use my laptop most of the time from flash drive is it harmful for my laptop ?
My Code is
import numpy as np
import cv2 as cv
img = cv.imread('img.jpg',0)
cv.imshow('image',img)
cv.waitKey(0)
cv.destroyAllWindows()
And the error is
Traceback (most recent call last):
File "opencv.py", line 5, in <module>
cv.imshow('image',img)
cv2.error: OpenCV(3.4.2) /tmp/build/80754af9/opencv-suite_1535558553474 /work/modules/highgui/src/window.cpp:632: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

If Python could not import the module virtualenvwrapper.hook_loader,check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/home/ujjwal/anaconda3/bin/python and that PATH is set properly.
